Hi Marton, Thanks to your comment I managed to get it worked. At least it outputs the results. However, what I need is to output each window result seperately. Now, it outputs the results of parallel working windows (I think) and appends the new results to them. For example, If I have parallelism of 10, then I will have at most 10 files and each file will grow in size as windows continue. What I want is, to have seperate file for a window. For example, after n'th window is computed output it to some file and close the file.
